To maintain Streaming media services flows friendly to TCP flows and h/ld the QoS of the streaming service in wireless networks

an adaptive rate control mechanism was proposed.Packet loss between.etwork congestion and wireless link error was distinguished to ’et the accurate state of the networks by the receiver.Occupati/n of the receiver buffer

which reflected how long the temporar)ly stored streaming medium data could be played

was also combined into this algorithm.And tradeoff between TCP-friendly and QoS of streaming media service was achieved through multi-level rate adjustment according to packet loss rate of congestion and queue length of receiver.The results of simulations show that good throughput was gained compared with TCP and TFRC

at most reaching 2M

in condition of 0-0.1 link drop rate

2 and 32 conncections.As link error and congestion was seperated by WTFCC

therefor

end to end packet drop rate was higher than TCP and TFRC

and also of higer throughput.Nomalized throughput indicated that WTFCC was friendly to TCP.
